What is a vegetarians? It seems like a simple question, but the answer is complicated because many people who follow very different diets all declare themselves vegetarians. Some, known as vegans, eat no animal products at all: no meat, no fish, no eggs, no products made from milk such as butter and cheese, and no honey. Some vegans, known as fruitarians go even further; they avoid killing plants, eating only fruit, seeds, beans and nuts. Other vegetarians are less extreme, eating no products that require killing animals. They decline to eat mear or fish but do eat milk products and eggs. Finally, there are vegetarians who eat some kinds of meat and fish. Some eat fish but no meat; some eat fish and chicken but no red meat such as beef. Because such people eat fish or chicken, strict vegetarian do not consider them to be vegetarians at all.
